<p>The <a href="qml-qtquick-openglinfo.html">OpenGLInfo</a> attached type provides information about the OpenGL version being used to render the surface of the attachee item.</p>
<p>If the attachee item is not currently associated with any graphical surface, the properties are set to the values of the default surface format. When it becomes associated with a surface, all properties will update.</p>
<p><b>Warning:</b> This type is deprecated. Use <a href="qml-qtquick-graphicsinfo.html">GraphicsInfo</a> instead.</p>
